Abstract:
The measurement of the energy flow is presented in the pseudorapidity range 3.15<η<6.63.15 < |\eta| < 6.6 in proton-proton collisions at the LHC for the centre-of-mass energy of s=13 TeV\sqrt{s}=13~\mathrm{TeV}. The data have been obtained during several periods of low luminosity operation in 2015. The energy flow, dE/dη\mathrm{d}E/\mathrm{d}\eta, as well as the transverse energy density, dET/dη\mathrm{d}E_\mathrm{T}/\mathrm{d}\eta, are studied as a function of pseudorapidity for soft-inclusive-inelastic and non-single-diffractive-enhanced events. The results are compared to models tuned to describe high-energy hadronic interactions and to earlier pp data at s=900 GeV\sqrt{s}=900~\mathrm{GeV} and 7 TeV7~\mathrm{TeV}. Comparison to the earlier data allows to test the hypothesis of the limiting fragmentation.
